ABSTRACT
Risk management of natural ground failures or those of anthropogenic origin by means of operational monitoring requires the setting-up of performing early-warning systems. The goal is to sufficiently anticipate the natural catastrophe, unpredictable in time, and thereby guarantee acceptance of the risks by effective reduction in the vulnerability, including the case of multiple risks and of domino effects. The supervision of a particular stake may be justified when it presents a high level of vulnerability. The necessity of having real-time information for monitoring the stake in the case of crisis management, is then determining. Active monitoring imposes to plan the measurements. Acquisition unit integrates a strategy of data acquisition rates locked on the progression of the monitored phenomenon. Smart coupling of passive and active monitoring, when set up on the site, is of an obvious interest for early detection and warning of ground movements. The coupling takes place both on the hardware and software levels.
